There are not really any long term effects for the use of shrooms and no known deaths attributed
to the use of them. Occasionally if someone takes shrooms who has a psychological problem they may become psychotic.

After using mushrooms containing psilocybin regularly for less then a week your body will build
up tolerance for the drug. This means that the user will not feel the high he is looking for from psilocybin. Usually the
user will stop ingesting these mushrooms for a few days so that he can again achieve the feeling that he wants.

Psychedelic

mushrooms do not seem to cause the physical dependance that other drugs such
as heroin and cocaine cause. But sometimes a user will think that they mentally need shrooms to achieve the feelings that
they may crave.
